coNrnoLLiNe Dnvior: ron s'rAariNG AND DnrnniirNiNe THE QANTITIES 'T0-BE DELIVERED :BY A Liourn aArsiNe APPARATUS PLACED Ar SAID DEVICE.

rIhe present invention relates to a device for controlling a liquid raising and measuring apparatus established at some distance from said device and consists in a graduated disk mounted in a casing and held in position by a ratchet stop-device against the action of aV spring, a jack providedwitli a handle serving as means for adjusting said disk to the desired number of measuring vessels and for starting the apparatus by uncoupling the disk i from the ack and by coupling this latter with a slide, the disk being returned stepwise `into its Zero position according to the n uniberof the delivered vessels whereupon the apparatus is stopped and the ack restored again into its initial coupled position.

In the annexed drawing one working torni of the device is represented as an example.

Fig. 1 shows the working position otparts and is a section on line l-I of Fig. 2 which is a rear view. y

Fig. 3 is a. section on line 111-111 of Fig. 1 seen from the left and with the wall plate 12 removed.

Fig. 4 is a similar section seen on line IV-V of Fig. 1.

Fig. 5 represents a detail and Fig. 6 a partv oi Fig; 1, showing the initial position ot parts,

. that is the positionroi' rest.

Figui' is a partial section on line VII-VII of Fig. 2.

ylhe principal portion ot the controlling device according. to the present invention is enclosed within a. casing` 1 closedv on one side by a hood 3' and on :the other side by a plate 41 which is secured to the back of a wallplate 42 while onnthe front side oil said wallplate are disposed the adjusting parts 4comprising a graduated rotatable disk 4e, .a conical jack lliinserted into said disk and a cover 2 ot' said disk provided with a window 10 showing onlya part of said graduation. Said disk is operated upon by a spiral spring 5 which is attached at one end to the wall plate 42 and at the other end .to the Adisks hub rand* is bent so as to turn the cover in .an anticlockwise sense. A pawl pivotally mount-4 ed within a hollow of said disks Vhub (Fig.v

3) engages under the effect of a spring 34 the inner teeth of' a ratchet-ring 6 the other teeth `of which are lengaged byv arocking-lever An initial -bend is given to spring .5 so that pawl 35 kis constantly trying to turn the .ring

6 in an anti-clockwise sense. But the turning of this ringinv this direction is prevented bya 9. The pitch ofthe inner teeth of ring'6 is seran' DISTANCE rnoivr half that of the outer teeth. Ifrocking-lever Z mountedon a square of aXis 10'is oscillat'ed its arms will act alternatelyiso as to allowrat each stroke and under the effect of spring 5 a turning movement of ring 6 for one tooth'at a time. N ow theaxis 10-ot` lever. is moved by means ot an arm 11 keptin 4contact with a piston 12 by a spring 32, saidpiston be-ing operateduponby a series of balls in the ball.-

tube 13 which is leading tothe liquid raising apparatus established at any distance from our device. The disk4v having aicentral conical boring is mounted on a conical jack 14 which is serving as a coupling means between disk and jack and extends tothe outside of the cover 2 where it is provided :with anadjusting handle or knob 15. The'j ack being hollow serves also as a guide for the hollow end of a cylindrical slide 16 .which isrextended' 'tl'irougli the .cenvterzof theidevice into the hood `U spring 17 which bea-rs with one .end on slide 16 and with the other Vend Von jack 1 1soas to keep .the latter .duringtlie posit-ion eotrest or,readiness-coupled with .the disk 4.

A two armed .trigger 19 (onlyV shown in Figs. 1 and 6) is pivotally mounted within al slot18 (Fig. 7) of slide 16 and extends inthe operative .position ot parts as shown inFig. 1 with a hook 2O and with al nose ;21 tothe outside oi' the path of slide 16,.` .Initliis .position hook 20engages under the .effect of a. spring. 36 the inner edge of `a sleeve 22 which Said hollow .end encloses a strong helical" is screwed tothe end 'of-jack r`leand -niain- I` `tains thereby the .coupling between'jack and slide'so .that the ei'ect of spring 17 isnulliiied during the operative position of parts. y

As unco'u-p'ling nieans between jack and slide .there isa smalllshaft 23 having .twov

catches 24- and 25. (Figs. 1, 41 and f6) jwliereot' catch 24 under @the .eii'ecto a'spring 34 lbears on the edge of a rim 26 and engages in the yposition of rest of the device thefnotch27 in said rim. In the .coupled state of ack-and slide'that Whencatch 24C is on theedge of 4rim 26, the other catchv25 is in contact with nose 21` of :the trigger so that whenevercatch lor) 24snaps linto the notcli27vcatch ,25 will lpush the trigger 19` inwards and disengage hook 20 from the rim of sleeve 22 and restore the effectiveness of spring which will cause the uncoupling of jack and slide so that knob retakes its initial position of rest.

A pin 29 (Fig. 5) embedded within aninsulating block 33 whichis fixed to`slide 16 'Y forms the contact member between two contacts 30 which are supported by a ring 31 ofinsulating material mounted between hood 3 and casing 1. This ring .carries also the i' Vterminals of the electrical leads connected to the electro-motor of the liquid raising apparatus. The operating means between the ball-,tube 13 and the liquid .raisinga'nd measure ing apparatus is not shown. It may consist ofan oscillating lever operated by the vdischarges ofthe measuring vessel, said lever `moving the balls within'tube r13 against the effect ofthe spring 32. Vhen spring 28 has friction with disk 4 and spring 17 presses the slide 16 into the hood 3 so that the block 33 of insulating material bears on a rim of said hood. The trigger 19 which is maintained in its disengaged position by sleeve 22 is partly introduced into an opening of the hood 3 as lshown in Fig. 6. YThen the contacts 29, 30 are broken.

. If a certain quantity of liquid which isv of A course always a multiple of the content of the measuring vessel has to be delivered knob 15 and therewith also jack 14 which under the 'effect of spring 28 is kept coupled likeY a wedge to the disk 4 is turned by hand if seen ,from the front side in a clockwise sense for so many teeth as there are measuring vessels to be delivered. By this operation notch 27 will be withdrawn from catch 24 and this latterwill bear on the surface of rim26 so `that catch 25 will no more hinder the axial movement of jack 14. This jack is now y Y pushed inwards by giving a tap on knob 15 causing hook 2O of trigger 19 to snapvover the inner edge of sleeve 22 (F ig. 1) thus coupling jack 14 with slide 16.

As the effect of spring 17 becomes nulliyfied by this operation spring 28 will become effective and will move slide 16 sothat pin 29 completes an electrical circuit between the contactsy 30y said movement being limited by the insulating vblock 33 which is arrested by a partitionwallv of the casing 1 in-order to bring nose 21 of the trigger 19 under the catch 25. The .closing of the circuit sets `effective again. Siide 16 will'be pushed again into the position of Fig. 6 where vthe electrical circuit is interrupted and the liquid raising apparatus will be stopped and ack 14 will be wedged again into disk 4 so'as to be coupled therewith. Thus the initial position oit' parts or the position of rest has-been restored again.

It` has been supposed here thatthe operating means of the liquid Vineasuring apparatus be an electro-motorgthe circuit of which isv under` thecontrol ofthe device according to the present invention.

This device however couldalso be employed if the operating means of the liquid measuring apparatus is a liand pump.l The slide 16 would in this case carry those members which allow or hinder the operating of said pump. VThis slide could for instance be adapted to cause the venting of the suction conduit of said pump inorder to prevent any liquid raising until the desired quantity has been adjusted on the new device.

Finally it could also be possible to combine the mechanical arrangement with the electric arrangement. 5 Y
